In my project i have used the JBPM5.3, mysql,tomcat, spring and hibernate, and the entityManagerFactory was made by spring .

and when i started a process by using the StatefulKnowledgeSession's startProcess method, then these table (task;i18ntext;peopleassignments_bas;content;peopleassignments_exclowners;peopleassignments_recipients;peopleassignments_stakeholders; ) were persisted

but the ProcessInstanceInfo table was empty .

      then i started another task ,and it was be OK ! but when i restarted the web server , the column processInstanceId in task table was restart from one , because of this ,i think the table ProcessInstanceInfo has some problem .

     in my opinion , i think when i start a task , then ProcessInstanceInfo is also must be persisted in the db ,because the ProcessInstanceInfo in the memory is not safe , it must be persisted in the db.

there some code about my project , sorry for my english.
